The 2 that I bought recently (Motorola and LG), as well as the MiFi device all have micro-USB connectors (and will work with the same chargers, both home and auto).
As to the electric dryers, I bought one in 1991 and another in 2007. Neither came with a cord.
** Here is a passage I lifted from a Mike Holt discussion, regarding this issue:
Article 250-60 in the 1993 code said that the frames of ranges and clothes dryers "shall be permitted to be grounded to the GROUNDED CIRCUIT CONDUCTOR if all of the conditions indicated in (a) through (d) below are met." Condition (c) states that "The grounded conductor is insulated; or the grounded conductor is uninsulated and part of a Type SE service-entrance cable and the branch circuit originates at the service equipment."
I think I mentioned it before, around here, the smallest aluminum SEU cable the inspection service will allow is #2. I would run that to the stove because it's cheaper than copper, which I think for a 50 amp load is #6.

"I've seen it for years but as of late the rule change calls for a four wire circuit. Years ago I installed a lot of dryers with 10/2 w/gr but now I use 10/3 w/gr or 8/3 w/gr. The smallest aluminum SEU you can run in a house around here is #2 which I often use for stoves. Moving an old dryer to a new location has us removing the old 3 wire cord and plug for the 4 wire cord and plug. I often run 10/2 w/gr to the disconnect for a
2 ton condensing unit and never bother to mark the white wire because it's in the same jacket as the black and ground.TDD"
RBM Here is the point in the thread were moving dryers was mentioned.

Missed that one.
I'm still having trouble believing that 10/2 w ground ws not code accepted at some point in the past. Just because I have seen so many of them. But I don't have copies of old code laying around to prove or disprove. And we all agree that any chanes require it be brought up to 10/3 w ground.
The other point is one I'm not sure about either. Does code require a white condutor be marked black if it is used as one leg of a 240 circuit?
Yes it is required to be reidentified. The only place where you didn't have to do it was in a switch leg using a cable (like Romex) but they plugged that hole in 1999. They still require that the white be used as the hot side of the switch leg, even when reidentified. That way the switched side will be the normal color at the light. (or other equipment)
Interesting. You sure don't find them re-marked in the real world much. At least not in residential anyway.
I believe that is part of the reason why NFPA closed the switch loop exception, so it would be uniformly required to always reidentify ungrounded conductors to something other than white.
really? typ. practice is to use black for hot and white for switched IME

It is not what the code says. The white gets connected to the hot side and the black is the switched leg so when it gets to the luminaire the installer is presented with a white and a black.
200-7(C)(2)Where a cable assembly contains an insulated conductor for single-pole, 3-way or 4-way switch loops and the conductor with white or gray insulation or a marking of three continuous white stripes is used for the supply to the switch but not as a return conductor from the switch to the switched outlet. In these applications, the conductor with white or gray insulation or with three continuous white stripes shall be permanently reidentified to indicate its use by painting or other effective means at its terminations and at each location where the conductor is visible and accessible.
As much as I hate to agree with this guy I can see a case for 14/2 that has both conductors with black insulation for switch runs. Personally I like to run the power to the switch box myself and that avoids the problem of a hot white.

** It would be impractical to have to carry a special cable just to run switch legs. You can always run a 3 wire cable and use red and black. The new Nec will be requiring a neutral at switch locations, so the problem will be eliminated anyway
I can see your point on "special" wire. Sharpie is a lot smaller.
Glad to hear about the code change. Reinforces my currrent practice :-)
Having a white neutral conductor in a 14-3 for switch legs makes it easy to install timers, lighted indicators and all sorts of controls for energy management in the switch boxes. I'm sure there are going to be a lot of energy management mandates showing up in building codes and specs for them in The NEC in the coming months and years if there are not already rules and laws in places like Californiastan. ^_^

A white wire can NEVER be used as a hot wire, and you have clearly and intentionally violated the law, and deserve prosecution to the fullest extent of the law.
Now that you have admitted your guilt to this criminal activity, the building inspectors will trace your internet service, come to this home, and arrest all occupants, along with condemning the home. You're in really big trouble. Don't be surprised if you find yourself looking down the barrel of several powerful firearms, held by U.S. Navy Seals, and if you resist arrest, they will not hesitate to shoot and kill you, just like Osama Bin Laden. You are a threat to society and must be prosecuted or eliminated.
ROTFLMAO, Send in Seal Team Six! The perp miss-wired a light switch!
That would probably be the reaction in a weird place like San Francisco. They would have to confiscate all computers, phones and electronic devices near the perp to make sure there are no other domestic terrorist plans extant. ^_^

It was never acceptable under the NEC.
Whoever sets the electrical rules where you are may have modified NEC, or inspectors may have used their discretion to allow it.
Depends on what "changes" you are talking about. Existing wiring with SE cable (or an insulated ground wire) is explicitly grandfathered in the NEC.
Running the power to the switch makes a less flexible condition. Places like bedrooms (although they are coming less and less with an overhead light) and living areas where you might want to add a ceiling fan would not have constant power at the light box.
That makes the most flexible condition.
In residential, smurf tube (ENT) is a good alternative to EMT. It gives you the flexibility without the hassle.
